Message-ID: <55495987.1090106@solarflare.com>
Date: Wed, 6 May 2015 01:00:07 +0100
From: Shradha Shah <sshah@...arflare.com>
To: David Miller <davem@...emloft.net>
CC: <netdev@...r.kernel.org>, <linux-net-drivers@...arflare.com>
Subject: [PATCH net-next 14/14] sfc: Bind the sfc driver to any available
VF's
Add the device ID of the VF to the PCI device ID table.
Added a boolean flag is_vf in efx_nic_type to differentiate
between a VF and PF at probe time. This flag is useful in later
patches while setting MAC address specially in the
PCI-passthrough case.
